Squeeze harder, feel more… and relax even more. The Gump Jumbo by Speks is for those who need just a little more. More volume, more resistance, and a more intense sensory experience in your hands.
This large gel stress ball completely fills your hand and provides deep, even pressure with every squeeze. This makes it particularly suitable for people who benefit from stronger stimuli to regulate tension or maintain focus.

The Jumbo variant moves slower and springs back calmly, naturally bringing you into a calm rhythm. Ideal for longer periods of concentration or when your body needs to release tension.
- provides deep pressure for extra sensory input
- helps regulate and release tension
- supports executive functions such as attention and self-regulation
- ideal for larger hands or intensive use
- great fidget for home, workplace, or therapy room

The sturdy gel filling remains flexible and resilient, even with intensive use. Like the smaller variant, it is easy to clean and designed to last with normal use.

A powerful fidget for those who are not satisfied with "just squeezing", but really want to feel what relaxation does.
